Im not sure when the Impellor was last replaced in my 03 Sunsation 288 w/ 496 Mag and i want to replace it this spring. This is my first 496 and i know the housing is brass and runs $400+, has anyone eve used one of the "rebuild" kits for this pump? JC Marine makes one that comes with new impellor, gaskets, wear plates etc....Also i dont like the idea of drawing the RV antifreeze up via muffs, i have read where guys install a tee fitting in the supply line just before the pump what kind of tee fitting do you use?

Here are some more

Buy the CPPerformane/Hardin Marine 496 stainless pump and you've solved all your current and future 496 raw water pump problems. This pump has the Raylar 496 Stamp of Approval.

+1, just bought this myself and it is really nice, this is also my first go round with the 496 pump so i haven't tackled it yet, any tips would be great!

just ordered the hardin marine $349 all stainless. Gonna put it on next week, plus the rebuild kits are cheap.

Been running the Hardin Marine stainless raw water pump now for a year and all good thus far! Caught a lot of flack for not buying a "rebuild kit" for the stock merc one. Was not a fan of grinding and silicone! The difference between the rebuild kit and the Hardin stainless entire replacement was only like a 250.00 bill! A LOT of material!!! Lovin it!

(also uses an old school impeller/much much larger and thicker internal shaft!).

I just bought 2 of the Gen 7s for my 502 mags
